Geobiologist, and Hayes Career Development Associate Professor in the Department of Earth, Atmospheric, and Planetary Sciences Tanja Bosak studies microbial fossils to understand the parallel evolution of life and the environment. She also undertakes laboratory experiments on modern microbes to test how they shape rocks and why microbes produce unique polycyclic lipid compounds that can persist in sediments for billions of years.
In this video interview she describes how her research contributes to unravelling the co-evolution of life and the environment on early Earth.
Professor Bosak, who received her PhD in 2004 from the California Institute of Technology, joined the EAPS faculty in 2007.
